EMPROVEMENT IN BRAKE-LEVERS.

Specification forming part of Letters Patent No. 190,458, dated May 8,1877; application filed December 18, 1876.

To all whom it may concern:

Be it known that I, ELISHA H. WHEELER, of Canton, Lewis county,Missouri, have invented certain new and useful Improvements inWagon-Brakes; and I declare the following to be a full and exactdescription thereof, reference being bad to the annexed drawings filedherewith, of which Figure 1 is a perspective of the wagonbrake. Fig. 2is a sectional view, showing the segments, lever, spring, shuttle andflanges. Fig. 3 is a top view of the shuttle. Fig. 4 is a section of thelever, showing the teeth.

The same letters and figures refer to like parts in the different views.

The nature of my invention consists in the construction of adouble-segment single-lever brake, provided with ratchet-teeth upon theinside surface of the outer segment, and in the construction of ashuttle carried by the lever between the two segments, so formed as topermit the teeth on the lever to engage the teeth of the segment on theforward movement of the lever, and to prevent them from coming incontact with the teeth of the segment on the return movement of thelever.

That others may make and use my invention, I will now more fullydescribe its construction and operation.

I make a segment, B, provided with collars E E and arm I I, upon whichis formed the hub O, which is reduced, as seen at 0, forming a shoulder,upon which is pivoted lever D. I then make segment A with ratchet-teethupon its inner surface, which teeth are marked 3 3, and are V formed onthe flange 13. Upon the lower edges of segments A and B I make flanges11 and 12, and upon the upper edge of segment B 1 make another flange. Ithen construct a shuttle, F, which conforms to the circle of thesegments A and B, and is provided with a shoulder, 5, upon its innerside, at the rear end of the shuttle. This shuttle is placed betweensegments A and B, and rests on flanges 11 and 12, as seen in Fig. 2.

tie F by coming in contact with F I then make a lever, D, with a hole atO, to fit onto shoulder O, and provided with a lug, H, to which isattached a connecting-rod. Upon lever D is formed teeth 4 4, made tomate teeth 3 3 of segment A, and upon the upper part of lever D isriveted a spring, 8, as seen in Fig. 2. X X shows a washer, resting onshoulder O, to secure the lever in place.

The several parts being made as described, the shuttle being placedbetween the segments, the lever is passed through the opening in theshuttle, and is secured in place on hub 0. The whole is then secured tothe Wagon-body by bolts passing through the segments at E E. Theconnecting-rod is then attached to lever D at lug H, and the lever D,being moved forward, carries with it the shut- When the lever arrives atthe teeth 3 3 on segment A, the spring 8 forces the lever againstsegment A, and causes the teeth of the lever to engage the teeth of thesegment.

When it is desired to release the brake, the operator, by a sidemovement, compresses spring 8, disengages teeth .1. 4 from teeth 3 3,the lever falls into recess 2 of the shuttle and rests on shoulder 5,which prevents the teeth of the lever and segment coming in contactduring the return movement.

What I claim as new, and desire to secure by Letters Patent, is-

1. Segment A, with its flanges l2 and 13, and ratchet-teeth 3 3 upon theinner side surface of the flange 13 at its forward end, in combinationwith segment B with its flanges 11 ll.

2. The shuttle F, in combination with segments A and B, and lever D.

3. The spring 8, in combination with segments A and B, lever D, andshuttle F.
